Analysis of A New Pilgrimage: Sonnet XXXVIII

I saw one sitting on a kingly throne,
A man of age, whom Time had touched with white;
White were his brows, and white his vestment shone,
And white the childhood of his lips with light,
Only his eyes gleamed masterful and bright,
Holding the secrets shut of worlds unknown,
And in his hand the sceptre lay of might,
To bind and loose all souls beneath the sun.
Where is the manhood, where the Godhood here?
The weak things of the world confound the wise.
Here is all weakness, let us cast out fear.
Here is all strength. Ah, screen me from those eyes,
The terrible eyes of Him who sees unseen
The thing that is, and shall be, and has been.
